Abstract

A sink includes a basin body having a generally concave shape that forms at least one sink basin, a top flange integrally formed with the basin body, the top flange extending around a rim of the at least one sink basin, the top flange having an underside that is generally flat, an apron connected onto a front portion of the underside of the top flange, and an adhesive disposed between the apron and the underside of the top flange to secure the apron to the basin body.

First claim

The invention claimed is:

1. A sink, comprising:
a basin body having a generally concave shape that forms at least one sink basin, wherein the basin body includes four side walls surrounding a floor that includes a drain opening, and wherein the four side walls are disposed along respective angled planes that converge in a vertical direction from the top flange towards the floor to form a generally inverted, truncated pyramid shape;
a top flange integrally formed with the basin body, the top flange extending around a rim of the at least one sink basin, the top flange having an underside that is generally flat;
an apron connected onto a front portion of the underside of the top flange, the apron including a front wall extending along the vertical direction and two side faces disposed along respective vertical planes that are angled relative to one another in a horizontal direction such that the vertical planes diverge in a rearward direction away from the front wall; and
an adhesive disposed between the apron and the underside of the top flange to secure the apron to the basin body;
wherein each of the basin body and the apron are made from an engineered stone material that is molded into a desired shape.

2. The sink of claim 1 , wherein each of the respective planes is inclined with respect to vertical at a draft angle, α.

3. The sink of claim 1 , wherein the basin body includes a channel extending along a front portion and, at least partially, along two side portions of the underside of the top flange.

4. The sink of claim 3 , wherein the channel is generally U-shaped and facilitates positioning, alignment and adhesion of the apron to the basin body.

5. The sink of claim 4 , wherein the apron has a generally flat shape formed by a front apron wall having two lateral along which two side faces are attached, and wherein the apron includes a reduced thickness flange, which has a thickness that is narrower than a width of the channel and is formed along a top end of the front apron wall.

6. The sink of claim 5 , wherein an outer edge of the reduced thickness flange of the apron abuts an outer wall of the channel.

7. The sink of claim 6 , further comprising a gap formed between an inner edge of the reduced thickness flange and an inner wall of the channel, the gap extending along the channel and configured to contain spillover of the adhesive on a rear side of the apron.

8. A sink, comprising:
a molded basin body having a generally concave shape that forms at least one sink basin, the sink basin having a bottom wall and at least four side walls, the at least four side walls being disposed along angled planes that converge in a downward direction;
a top flange integrally formed with the basin body, the top flange extending around the at least one sink basin and being disposed along a horizontal plane;
a molded apron connected to a front portion of the top flange, the flange including two side faces disposed along angled planes that diverge in a rearward direction towards a rear of the sink such that they present vertical edges when viewed from a front of the sink.

9. The sink of claim 8 , wherein the molded basin body is formed in a first mold having at least two pieces that separate in a vertical direction with respect to the sink, and wherein the molded apron is formed in a second mold having at least two pieces that separate in a horizontal direction.
